Édouard Branly

Édouard Branly was a French physicist and physician, professor at the Institut Catholique de Paris, whose 1890 discovery of radioconduction produced the detector that made wireless telegraphy possible.

Édouard Brézin

Édouard Brézin, born in 1938, is a French theoretical physicist known for statistical field theory, the renormalization group, and random matrix theory, with work important to string theory.

Édouard Goursat

Édouard Goursat (1858–1936) was a French mathematician, professor at the Sorbonne, remembered for proving Cauchy's integral theorem without assuming continuity and for his three-volume Cours d'analyze mathématique.

Edouard Zeckendorf

Edouard Zeckendorf (1901–1983) was a Belgian physician, army officer, and amateur number theorist from Liège known for Zeckendorf's theorem, which gives every positive integer a unique representation as a sum of distinct, non-consecutive Fibonacci numbers.

Edrophonium

Edrophonium is a short-acting acetylcholinesterase inhibitor, acting within 30 to 60 seconds, that raises acetylcholine at the neuromuscular junction, the basis of the Tensilon test for myasthenia gravis, discontinued in the United States in 2018.

EDTA and its salts

EDTA (edetic acid, CAS 60-00-4) and its sodium, calcium, and iron salts are hexadentate chelating agents used in detergents, food, medicine, and oilfield work, valued for strong metal binding but scrutinized for persistence and poor biodegradability.

Eduard Buchner

Eduard Buchner (1860–1917) was a German chemist who showed in 1897 that cell-free yeast extract ferments sugar to alcohol, disproving vitalism and winning the 1907 Nobel Prize in Chemistry.
